9e0be36948 Avoid recording unnecessary deoptimization environments in a couple of places. 
This reduces the number of uses and potentially shortens live ranges.

03c737625a Make sure transitioned arrays efficiently call builtin Array functions 
Loosen the requirement for Map equivalency on several map checks, including checks up the prototype chain, that are not sensitive to ElementsKinds. These selected map checks should also match against FAST_DOUBLE_ELEMENT and FAST_ELEMENT transitions of the original map. This specifically helps all variants of transitioned JSArrays to still efficiently call builtins like push, pop and sort.

c4d3a110a2 Adjust position recorded for call expressions. 
For calls of the form ident(...) record position of the identifier as the position of the call. For other calls record positions of the opening parenthesis.

This guarantees that for expressions of the form function(){}() call position will not intersect with positions recorded for function literal which is used by the debugger for scope chain resolution.

81a0271004 Randomize the seed used for string hashing. This helps guard against 
CPU-eating DOS attacks against node.js servers.  Based on code from
Bert Belder.  This version only solves the issue for those that compile
V8 themselves or those that do not use snapshots.  A snapshot-based
precompiled V8 will still have predictable string hash codes.
